1. The Great Pyramid of Giza is completed for Pharaoh Khufu 2560 BCE

   It remained the tallest human-made structure on Earth for about 3,800 years, until Lincoln Cathedral's spire topped it in the 1300s.

2. William the Conqueror defeats King Harold at the Battle of Hastings 1066

   The Bayeux Tapestry — actually an embroidery nearly 70 meters long — tells the story, including Harold's famous (and disputed) arrow in the eye.

3. Charles Darwin publishes On the Origin of Species 1859

   'Me at the zoo' is nineteen seconds of co-founder Jawed Karim standing in front of elephants in San Diego, noting they have 'really, really long trunks.'
